Be' it l'rnown that I',-:.En'wrN E; SLICK, of Pitt's urgh, in the county of Allegheny and State: oflennsylvania, have invented a new and useful Method ofFinishing Car-Wheels, of which the followingis afull, clear, and exact description, reference being had to the accompanying drawing, specification. v

This invention relates to the manufacture offorg'ed metal car Wheels and more particularly relatesto-finishing the Wheels after thezcompletion of the forging operations.

In the manufacture. of. metal car Wheels forging, a fin, which may. ex'tend teither wholly or partly around the periphery of the Wheel is usually formed on the periphery of the Wheel duringsu'ch' forging Operations.

After the severing operation is completed the carrier 8 is caused to rotate through another part of a' revolution so as to bring the wheel from which the fin has just been removed into position above the anvil block 20 in range of the punching pin 15 of the punching mechanism, this pin then being in the'position relative to the wheel shown in Fig.3. The fluid pressure cylinder 16 is then supplied with fluid pressure so as to advance the ram 17 on which the pin 15 is mounted and move the pin 15 from the position shown in Fig. 3 into that shown in Fig. 4, by the downward movementof the punching pin completing the axle eye in the hub of the wheel and forcing the. pin 18 from the wheel. While the hub of the wheel is being punched another wheel is being sheared. During the time the fin is being removed from a wheel, and another wheel is being punched, a punched wheel is being removed from the support 8 and a forged wheel which has just been completed, while still hot from the forging operation, is put into place on the support 8 in readiness to be moved into position to be sheared. The support as shown is equipped to hold three wheels, one in position to be. sheared, one in position to be punched, and a third wheel which is being placed upon or removed from the carrier while the shearing and punching operations are being performed.

It is desirable to finish the wheels so that the hub length of successive wheels will be uniform, and. in order toaccomplish this result, means are providedfwhich, as shown in Figs. 3 and 4:, consistina die face 19 removably supported on the stripping mechanism. 20. When the ram' 17. lsadvanced so as to complete the axle eye in the hub of the wheel and after the eye is completedand the pin 18 removed from the hub of the wheel, the downward movement of theram 17 is continued until the lower end of the ram engages with the stripper 20. By c0ntinuing-the downward movement of the ram with the stripper 2O the die face 19 is moved from the position shown'in Fig. 3 into that shown 1n Fig. this movement continuing for the full length ofthe stroke of the ram 17 and fixing, the length of the axle eye of. the wheels. It will be noted that the support-14 is held out of engagement with the 'top face of the carrier 8 as is shown in Figs fland tools is removed and the cost 1 I claim 2+ In the manufacture of 3 and that the lower face of the support- 14 does not contact with the top face of Y the anvil block 20 while the support 8 and carrier 14; are being moved into position above the anvil block. When the ram is advanced so as to begin the operation of completing the axle eye the lower face of the support l l 'is'moved into contact-with and is supported by the top face of the anvil block 20 during the punching or'eyeforming movement, this being clearly shown in Fig. &.

In some cases wheels will be forged with the axle eye formed therein and in other cases the wheels may be forged and the wheel formed, and the wheels afterward reheated and the fins removed; In such cases, there not being a pin in the axle eye, it

will be necessary to place thewheel'upon a pin so as to center itfon the support 8 during the shearing operation. In such cases I preferably employ a pin 18 such as is shown in Fig. 2, this pin being removably secured in and forming part of the support The advantages of my invention will be apparent to those skilled in the art. By the use of my improved method the hubs ofthe wheels are completed in readiness for the boring operation by which a wheel fit is made, fins formed during the forging operations are quickly removed, and the hubs are sized to a fixed definite length at the same heat by which the forgingo eration is carried out.

operations by means of. slow speed machine forged wheels is largely reduced.
